Abstract

A starting apparatus includes a drive motor and a reduction gear having a planetary gear for starting an engine by the drive motor via the reduction gear. An internal gear of the reduction gear includes a locking projection projecting in an axial direction. A rotation restricting member is formed with a guide groove in which the locking projection is loosely received and guided in a circumferential direction. A shock absorbing member is held in the guide groove in a state of being elastically in close contact with the locking projection in the circumferential direction. Thus, shock load to the internal gear is alleviated from the start.
